T 0 all whom it may concern:

Be it known that l, SERGE on Pnoooonmn- U'OIZSKY, a Russian subject,residing at present atGranstad, Konnerud, near Drammen, Norway, haveinvented certain new and useful Improvements in Apparatus for theTreatment of Photographic Negatives or the like with Liquids; and I dohereby declare the followingto be a full,-olear, andexact description ofthe invention, such as Wlll enable others skilled in the to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

The present invention relates to an apparatus for the treatment ofphotographic negatives with water or other liquids in which the liquidand the objects treated have a motion relatively to each other. Anapparatus constructed in accordance with the invention is illustrated onthe annexed drawing, in which Figure 1 is a side view partly in verticalsection. Fig. 2 is aplan view, while Figs. 3 and f show a verticalsection and a plan view respectively of a stand or frame carrying theobjects to be treated and to be put in the liquid-container.

In the illustrated example the apparatus consists of a tank (A) which isprovided at its bottom and top with pipes (1) and (2) through which theliquid enters and leaves the'tank. The tank is closed by means of ahinged cover (3) which is locked by means of a spring-pressed bolt (5)and keeper (6). The center of the cover is provided with a shell (8),carrying the rotary shaft (7), the lower part of which is fitted with across-bar (9) having pins (10).

The shaft (7) carries a worm-wheel (11) outside the tank, which mesheswith the worm (12) on the axle (13). The small toothed wheel (14) on theaforesaid axle engages with the toothed wheel (15), when the cover islocked. The toothed wheel (15) is keyed on to the boss of the pulley(16), which rotates free on the pin (17), fixed to the tank. A stand 13(Figs. 3 and 4-) is placed in the before mentioned tank, said standconsisting of upper and lower spiders (20) connected by rods (19) andcarrying an inner rotating frame, which is provided with hearing shafts(21) and (22). This frame co aprises rods (24) which have cuts or kerfs(28) on the inner side. One of the rods is connected with the uppercrossshaped piece (23) by means of the oint (27) and it is kept inposition at the lower crossshaped piece (23) by aid of the spring-latch(26). On the upper bearing shaft (21) of the supporting frame across-piece is arranged, which is in level with the aforesaid pins (1.0)on the axle ('7), when the stand B is placed in the basin A.

The products or objects which are to be treated, for instancephotographic negatives are put in between the kerfs (28) on the rods (2either horizontally in the frame (23, 24) or in an inclined position. Toenable the negatives to be put in place, one of the rods (24) is swungout on hinge (27) and after the negatives are in place such rod isreturned to the position shown in Fig. 8 where it is held by springlatch (26).

The projecting blocks or disks (29) in Fig. 3 which are arranged abovethe ed e of the frame are made of ebonite, indie-rubber, guttapercha, ora similar elastic material and are arranged with the object of avoidinthe tank A. being scratched by the frame g when same is put in or takenout of the tank, similar blocks or disks (30) being arranged on thebottom of the frame.

)Vhen the frame B with the objects, which are to be treated are put inthe tank A and the cover (3) has been locked, the axle (7) is put inmotion which in its turn transfers the motion to the frame (23, 24) bymeans of the pins (10). The objects put in the frame B are thus kept inmotion within the liquid, with the result that they will uniformly andcontinuously come in contact with different portions of the liquid. Therotation of the pulley (16) is transferred to the axle (7) in such a waythat the latter is caused to rotate slowly.

Instead of using a worm gearing for this speed reduction, any othersuitable mechanism may be used.

I claim as my invention 1. In apparatus for treating photographic platesand the like with liquid, the combination of a container having inletand outlet pipes for the liquid; a cover on said container; a shaftcarried by said cover and extending into the container; means forrotating said shaft; a removable stand in said container; a framerotatably mounted in said stand and having means for supporting theplates Within it; a cross-piece connected to the upper end of saidframe; and driving means carried by said shaft for engagement With saidcross-piece.

2. In apparatus for treating photographic plates and the like withliquid, the combination of a container having inlet and outlet pipes forthe liquid; a cover on said container; a shaft carried by said cover andextending into the container; means for rotating said shaft; a removablestand in said container and having members for carrying the platesbetween them, one of said members beingremovably fitted in the frame toenable the insertion of the plates therein; a cross-piece connected tothe upper end of said frame; and driving means carried by said shaft forengagement with said crosspiece.

3. In apparatus for treatlng photographic plates and the like Withliquid, the combination of a container having inlet and outlet pipes forthe liquid; a cover on said container; a shaft carried by said cover andextending into the container; means for rotating said shaft; across-piece connected to the lower end of said shaft; a removable standin said contain r; a rotatable frame in said stand having upper andlower bearing shafts engaged therewith, said frame having means forsupporting the plates therein; a cross-piece connected to the upperbearing shaft; and driving means connecting said cross-pieces.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing Witnesses.
